Answer:

B'(6, 6) ; C'(12, 6)

Step-by-step explanation:

The points are not labeled so I'm going to assume the points are as follows:

A(3, 9)

B(3, 3)

C(6, 3)

In order to dilate with a scale factor of 2, simply multiply the x and y coordinates by 2.

B(3, 3) ⇒ B'(6, 6)

C(6, 3) ⇒ C'(12, 6)

Determine the center and radius of each circle.<br> (x – 6)2 + y2 – 8y = 0
rusak2 [61]

Answer:

Step-by-step explanation:

(x-6)² + y²-8y = 0

Put the equation into center-radius form.

complete the square

 coefficient of the y term:  -8

 divide it in half: -4

 square it: (-4)² = 4²

 add 4² to both sides to complete the square and keep the equation balanced:

(x-6)² + (y²-8y+4²) = 4²

(x-6)² + ( y-4)² = 4²

center (6,4)

radius 4
